loadMovie vs loadMovieNum , again :(

Hello

I thought I understood this but I now realise that I am confused. I am trying to load movies into a host blank movie clip. I can do it OK but I got a little distracted about all the target and level options …

  1. What is the difference between

loadMovie( "some_movie_to_load " , “emptymovieclipholder”);

and

empty_movieclip_holder.loadMovie(“some_movie_to_load” , 0);

Both of the above work in my situation, maybe there isn’t a difference.

  1. Why can I not have this …

empty_movieclip_holder.loadMovieNum(“some_movie_to_load”, 0);

Thank you kindly for any help.
